A system and method for a connected wireless device to hand off from one network to another based on empirical data gathered from real live networks regarding the grade of service available on the network. The invention uses this information in combination with the user's choice of a preferred type of network connection to intelligently manage and conserve device battery life.

System for eco-friendly management of connected devices

A system and method for a block based differencing algorithm which includes the ability to limit memory requirements regardless of source file sizes by splitting the source file into optimally sized blocks. The invention allows the blocks to be processed in any order allowing in-place operation. Further, the present invention allows a second stage compressor to match the compressor blocks to those used by the differencing algorithm to optimize compressor and decompressor performance.

Block-based differencing algorithm

A method to efficiently detect, store, modify, and recreate fully or partially duplicate file forks is described. During archive creation or modification, sets of fully or partially duplicate forks are detected and a reduced number of transformed forks or fork segments are stored. During archive expansion, one or more forks are recreated from each full or partial copy.

Efficient full or partial duplicate fork detection and archiving

A system and method for losslessly compressing already compressed files, such as JPEG files. The inventive method involves full or partial decompression of the original file, and re-compression using various advanced data compression techniques. Decompression involves decompression using the advanced techniques and re-compression using the original techniques. This method and system saves on data storage space and allows for the reconstruction of an original compressed file for use in applications that require or support the original compressed format.

System and method for lossless compression of already compressed files

A system and method for the detection, compression, and decompression of previously compressed data that resides in data or files of an unknown data or file format.

Detection and recompression of embedded compressed data inside existing data streams

A method for improving lossless image compression by using multiple lossless image compression techniques and adapting the best one to each image. An RGB compressor receives an image file and splits the image into rectangular block types. Different digital image and/or sub-image (block) types are optimally compressed using a compression techniques particularly well-suited for the particular kind of image or block.
